Hi Mik

You´re welcome.
If theres anything else i can do please let me know.

If you find yourself in a pinch for basic parts i might be able to help out. I do have a lathe and a mill so...

Anyways... Merry christmas. If you celebrate christmas that is

Hi and thank you for the answer!
I had a bit of free time so i tried to make something myself, just to go on a bit with the code... here's the result:

The microservos are just glued but it's ok in my case, hope this could be usefull for someone else.

Thank you again,
Mik

Hi Horizon.

I just thought i'd let you know that i just went through the exact same thing. From what i can tell all four grippers of this type i could find was just about the same size. I couldn't find anything using micro servos.
However the spline head of the servos are quite often the same size for standard and micro servos so you should be able to replace the full size with a micro and just fill in the side gaps with plastic, glue or whatever.
Keep in mind though that replacing the servo will only give you about 1cm reduction in height. the width will remain the same.

Kindest Regards
/Stig.

Hi and sorry for my bad english

I'm a coder without any electronic experience, i dont have a cnc machine so when i need robot parts i have to buy.

This is the second robot that i build, the first one was a boe-bot and all the parts was ready to be assembled from a beginner with just a screwdriver.

This one is coming from my immagination and i'm facing a big problem trying to find a gripper that can fit in the small space available under the head.

Small video of the robot working: http://www.youtube.com/watch?v=kWG2EbhZUgc

I seen the pob gripper in this store and i falled in love for its design

The only problem is that those seems normal size servos so the entire gripper seems to be larger than the entire neck/head block of my robot... someone know the exact size of it?

Really, the design of the pog gripper is perfect but i need to know if there is something smaller on the market or if could be possible, in some way, to decrease the size of the pob gripper replacing the servos with microservos and, maybe, bending a little the metal of the structure with my advanced tools ( a clamp and a screwdriver).

Thanks in advance,
Mik
